You do not have to go far in Liverpool to spot Jurgen Klopp's influence.
You can drink in a pub bearing his name, you can sleep in a guest house named after him, in several areas you can see bare bricks covered in paint, brought to life by his image.
And Klopp has brought life to the city, for those of a red persuasion at least.
He has served up an energy, poured it into the Anfield crowd and carried with him a sea of believers.
The man is full throttle, his teams play in his image and the stands at the ever-changing stadium feed off a power source that seemingly starts with him.
He would likely play down such significance but this day will hurt fans. Some will remember the footage of supporters being informed on the streets of Liverpool of Bill Shankly's retirement. They were disbelieving, frozen in an age where access to instant information was not the norm.
Others will recall the exit of Sir Kenny Dalglish, the loss of an adopted son of the city. Each recollection brings its own pain and new era - good and bad.
Some - perhaps Klopp himself - will preach the need for continuity. Fans who have felt the force of his energy will truly question if such a one-off can be followed with any semblance of what has gone before.
In all reality, everything will now change. Klopp turned doubters to believers. Someone will need to carry fans up that mountain once again.
Klopp painted the Reds consistently back into the competitive picture. His legacy will manifest in the trophy room, on city walls and, perhaps most importantly of all, in hearts.
